5、-06 Superseding J1323 MAY2009 Standard Classification System for Fiberboards RATIONALE J1323 has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE This SAE Standard provides a means for specifying or describing the pertinent properties of fiberboards for automotive application
6、s. The materials normally specified by this standard are defined in SAE J947. The test methods commonly used for fiberboards are defined in SAE J315. 1.1 Purpose The purpose of this classification system is to provide guidance to the engineer in the selection of commercially available fiberboards an
7、d further provide a method for specifying the fiberboard and its critical properties by use of a standard line call-out. 2.

NUMBERING SYSTEM 3.1 The Basic Five Characters This classification establishes alpha-numeric characters for various performance levels of each fiber
12、board property or characteristic. In specifying or describing fiberboard materials, each line call-out shall include the number SAE J1323, followed by a sequence of alpha-numerics to describe the fiberboard and its properties. The first five alpha-numeric characters of the call-out after SAE J1323 a
13、re mandatory, since they identify the material and specify the critical fiberboard properties, thickness, fiberboard type, and dimensional stability. 3.2 Suffix Letters To further specify or describe the fiberboard, each line call-out may include one or more suffix - alpha-numeric symbols as listed
14、in Section 5. These suffix letters, when appended to the basic number, specify additional physical or mechanical property requirements. Suffix symbols may be used singly or in combination to describe the properties desired in the fiberboard. 3.3 Special Numbers The numeral 0 is used when the descrip
15、tion of any characteristic is not desired. The numeral 9 is used when the description of any characteristic (or test related thereto) is specified by some supplement to this classification system, such as notes on engineering drawings. 3.4 Special Letter To identify other characteristics not covered
16、 by the existing suffix symbols, the letter Z shall be used. The Z characteristics shall be specified in detail on the engineering drawing or other supplement to this classification. If more than one Z characteristic is specified, they should be identified by subnumeral, for example, Z1, Z2, Z3, etc
17、. 3.5 Example The line call-out SAE J1323 B2A23A1B7C3D9Z would be broken down to indicate the type of fiberboard and properties as in Figure 1: SAE INTERNATIONAL J1323 Reaffirmed JUN2014 Page 3 of 8 FIGURE 1 - LINE CALL-OUT DETERMINATION By using the breakdown in Figure 1 and Tables 1 to 4, the exam
18、ple line call-out specifies a hardboard, 2.03 mm thick, with a 0.5% maximum expansion and a 0.75% maximum contraction after humidity exposure. The optional requirements include a weight of 1 kg/m2 0.05, a moisture content of 5 to 9%, water absorption of 30% maximum, and a special modulus bending req
19、uirement. 4. BASIC FIBERBOARD CHARACTERISTICS Fiberboards identified by this classification system shall have the following three basic characteristics indicated by the first five alpha-numeric symbols. 4.1 Fiberboard Type The first character of the line call-out specifies the type of fiberboard as
20、defined in SAE J947, and listed in Table 1: TABLE 1 - FIBERBOARD TYPE DETERMINATION First Character Fiberboard Type A None Specified B Hardboard C Paperboard Laminated D Paperboard Single Ply E Paperboard Wet Machine Board F Molded Cellulosic Fiber Pulp Product G Kraft Paper H Paperboard Corrugated
21、Z Special Requirements, as Necessary 4.2 Thickness The second character of the line call-out specifies the fiberboard thickness in millimeters as determined in SAE J315, and listed in Table 2. The thickness tolerance for paperboard is 5% from the average panel thickness; however, the thickness varia
22、tion within a hardboard panel (in the range of 1.65 to 3.18 mm thick) is 0.25 mm from the average panel thickness.

25、he third, fourth, and fifth characters of the line call-out specify the maximum1percent expansion and contraction of the fiberboard for both the machine and across-machine direction, as determined in SAE J315, and listed in Tables 3 and 4. The third character denotes the method of test in SAE J315,
26、the fourth character specifies the maximum expansion, and, the fifth character specifies the maximum contraction.
